BACKGROUND

The present invention relates generally to a system and method fordelivering a weapons system with an unmanned vehicle, more specifically,to a system and method for mounting and deploying a weapons systemautonomous or semi-autonomous vehicles.

Autonomous or semi-autonomous vehicles, also referred to as unmannedaerial vehicles (UAVs), remotely piloted aircraft (RPA) and autonomousground vehicle (UGVs), are a small, typically portable, vehicle thathave found a variety of uses in commercial and military application,such as but not limited to surveying, surveillance, aerial photography,and package delivery. A UAV typically consists of a body, a device suchas a camera, a navigation system, and a propulsion system. Thepropulsion system usually consists of a plurality of rotors (e.g. four)that generate lift in the same manner as a helicopter. The vehicle islaunched and is either guided by an operator or follows a path usingnavigation techniques to an end location. The vehicle then performs atask (e.g. photographs an area) and then returns to a landing site. Inthe case of UAV's and RPA's that include ordnance, the vehicle wasexpendable and did not return from the mission.

Accordingly, while existing autonomous or semi-autonomous vehicles aresuitable for their intended purposes the need to improvement remains,particularly in providing a weapons platform having the featuresdescribed herein.

In an embodiment, the drone 20 includes a plurality of thrustdevices 24A, 24B, such as four thrust devices arranged about theperiphery of the fuselage 22. In an embodiment, the thrust devices 24include propeller member that rotates to produce thrust. The thrustdevices 24 may be configurable to provide both lift (vertical thrust)and lateral thrust (horizontal thrust). The vertical and horizontalcomponents of the thrust allow the changing of the altitude, lateralmovement and orientation (attitude) of the drone 20.

In the exemplary embodiment, the fuselage 22 and thrust devices 24 aresized and configured to carry a system 30 having a payload 26. Thepayload 26 being releasably coupled from the fuselage 22 duringoperation. As will be discussed in more detail herein, the system 30further includes a payload control module 32 and an attachment plate 34.The attachment plate 34 includes a mechanical connection 28 that fixedlyand removable couples the plate to the drone 20. The mechanicalconnection 28 may include a means, such as multiple bolt hole patternsfor example, that allows the plate 34 to be coupled to a variety ofdifferent unmanned vehicles. The mechanical connection 28 further allowsfor the removal of the system 30, such as in the event that either thedrone 20 or the system 30 is damaged. As discussed in more detailherein, the attachment plate further includes one or more features thatallow the payload to be at least partially armed and allow the payloadto be releasably coupled to the attachment plate 34.

The drone 20 includes a controller 38 having a processing circuit. Thecontroller 38 may include processors that are responsive to operationcontrol methods embodied in application code, such as for navigating thedrone 20. These methods are embodied in computer instructions written tobe executed by the processor, such as in the form of software. Thecontroller 38 is coupled transmit and receive signals from the thrustdevices 24, the transfer member 34 and the coupling device 36 todetermine and change their operational states (e.g. extend transfermember 34, change polarity of coupling device 36, adjust lift fromthrust devices 24). The controller 38 may further be coupled to one ormore sensor devices that enable to the controller to determine theposition, orientation and altitude of the drone 20. In an embodiment,these sensors may include an altimeter 40, a gyroscope or accelerometers42 or a global positioning satellite (GPS) system 44.

FIG. 2 illustrates a block diagram of a controller 38 for use inimplementing a system or method according to some embodiments, such asthe control module 32 for example. The systems and methods describedherein may be implemented in hardware, software (e.g., firmware), or acombination thereof. In some embodiments, the methods described may beimplemented, at least in part, in hardware and may be part of themicroprocessor of a special or general-purpose controller 38, such as apersonal computer, workstation, minicomputer, or mainframe computer.

In some embodiments, as shown in FIG. 2 , the controller 38 includes aprocessor 105, memory 110 coupled to a memory controller 115, and one ormore input devices 145 and/or output devices 140, such as peripheral orcontrol devices, that are communicatively coupled via a local I/Ocontroller 135. These devices 140 and 145 may include, for example,battery sensors, position sensors (altimeter 40, accelerometer 42, GPS44), indicator/identification lights and the like. Input devices such asa conventional keyboard 150 and mouse 155 may be coupled to the I/Ocontroller 135 when the drone is docked to allow personnel to service orinput information. The I/O controller 135 may be, for example, one ormore buses or other wired or wireless connections, as are known in theart. The I/O controller 135 may have additional elements, which areomitted for simplicity, such as controllers, buffers (caches), drivers,repeaters, and receivers, to enable communications.

The I/O devices 140, 145 may further include devices that communicateboth inputs and outputs, for instance disk and tape storage, a networkinterface card (NIC) or modulator/demodulator (for accessing otherfiles, devices, systems, or a network), a radio frequency (RF) or othertransceiver/communications-circuit, a telephonic interface, a bridge, arouter, and the like.

The processor 105 is a hardware device for executing hardwareinstructions or software, particularly those stored in memory 110. Theprocessor 105 may be a custom made or commercially available processor,a central processing unit (CPU), an auxiliary processor among severalprocessors associated with the controller 38, a semiconductor basedmicroprocessor (in the form of a microchip or chip set), amacroprocessor, or other device for executing instructions. Theprocessor 105 includes a cache 170, which may include, but is notlimited to, an instruction cache to speed up executable instructionfetch, a data cache to speed up data fetch and store, and a translationlookaside buffer (TLB) used to speed up virtual-to-physical addresstranslation for both executable instructions and data. The cache 170 maybe organized as a hierarchy of more cache levels (L1, L2, etc.).

The memory 110 may include one or combinations of volatile memoryelements (e.g., random access memory, RAM, such as DRAM, SRAM, SDRAM,etc.) and nonvolatile memory elements (e.g., ROM, erasable programmableread only memory (EPROM), electronically erasable programmable read onlymemory (EEPROM), programmable read only memory (PROM), tape, compactdisc read only memory (CD-ROM), disk, diskette, cartridge, cassette orthe like, etc.). Moreover, the memory 110 may incorporate electronic,magnetic, optical, or other types of storage media. Note that the memory110 may have a distributed architecture, where various components aresituated remote from one another but may be accessed by the processor105.

The instructions in memory 110 may include one or more separateprograms, each of which comprises an ordered listing of executableinstructions for implementing logical functions. In the example of FIG.2 , the instructions in the memory 110 include a suitable operatingsystem (OS) 111. The operating system 111 essentially may control theexecution of other computer programs and provides scheduling,input-output control, file and data management, memory management, andcommunication control and related services.

Additional data, including, for example, instructions for the processor105 or other retrievable information, may be stored in storage 120,which may be a storage device such as a hard disk drive or solid statedrive.

In other embodiments, the display 130 may includea plurality of LED status lights (e.g. visual indicator 558, FIG. 5 ).In some embodiments, the controller 38 may further include a networkinterface 160 for coupling to a network 165. The network 165 may be anIP-based network for communication between the controller 38 and anexternal server, client and the like via a broadband connection. In anembodiment, the network 165 may be a satellite network. The network 165transmits and receives data between the controller 38 and externalsystems. In an embodiment, the external system may be another aerialdrone or a drone docking system. In some embodiments, the network 165may be a managed IP network administered by a service provider. Thenetwork 165 may be implemented in a wireless fashion, e.g., usingwireless protocols and technologies, such as WiFi, WiMax, cellular,satellite, etc. The network 165 may also be a packet-switched networksuch as a local area network, wide area network, metropolitan areanetwork, the Internet, or other similar type of network environment. Thenetwork 165 may be a fixed wireless network, a wireless local areanetwork (LAN), a wireless wide area network (WAN) a personal areanetwork (PAN), a virtual private network (VPN), intranet or othersuitable network system and may include equipment for receiving andtransmitting signals.

Referring now to FIG. 3 and FIGS. 4A-4C, an embodiment is shown of adrone 320 that includes a weapons system 330. In an embodiment, thedrone 320 may be a Pegasus unmanned aerial vehicle manufactured byRobotic Research LLC of Clarksburg, Md., USA. The drone 320 issubstantially similar to the drone 20 of FIG. 1 . In an embodiment, thedrone 320 is configured to switch between aerial vehicle and groundvehicle operations. The drone 320 includes a fuselage 322 and aplurality of thrust devices 324.

In an embodiment, the weapons system 330 includes an attachment plate334. In an embodiment that system 330 includes a single attachment plate334 that multiple control modules 332 and multiple energetic modules 326are attached. As used herein, the term “payload module” refers to anassembly consisting of a control module and an energetic module. Inanother embodiment multiple attachment plates 334 are provided and eachattachment plate 334 has an associated control module 332 and payload326. In the example embodiment, while the weapons system 330 is coupledto the drone 320, the weapons system 330 is functionally independentfrom the drone 320. In other words, there is no power, communications,or data transfer between the drone 320 and the control module 332 orenergetic module 326. It should be appreciated that this independenceallows the weapons system 330 to be coupled or redeployed to differentdrones without needing to reconfigure or alter the weapons system 330.As will be discussed in more detail herein, when the payload module iscoupled to the attachment plate 334, a key FOB 377 is disengaged fromthe control module and may be removed by the operator (FIG. 4C). In anembodiment, when the key FOB 377 is coupled to the control module, theenergetic module 326 cannot be activated.

Referring now to FIG. 5A, FIG. 5B, and FIG. 6 an embodiment is shown ofthe payload module 530. In this embodiment, the payload module 530includes a energetic module 526 and a control module 532. The energeticmodule 526 includes a housing 540. In an embodiment, the housing 540 hasa generally cuboid shape and contains an energetic 541, such as but notlimited to polymer-bonded explosive (PBX) or thermite for example.Arranged on at least one end 542 is a latch 544 that interconnects andfixes the housing 540 to the control module 532. The latch 544 includesa slidable lever that engages a locking element 550 in the controlmodule 532. It should be appreciated that in other embodiments, othertypes of locking elements 550 may be used. In an embodiment, the housing540 includes a cover 546 having a coupling element 548. In anembodiment, the coupling element 548 slidably couple the housing 526 tothe control module 532 (FIG. 5B). In an embodiment, the coupling element548 has a dovetail shape. In an embodiment, the energetic module 526 isremovably coupled to the control module 532, which allows for differentenergetics to be coupled to the payload module 530. To replace theenergetic module 526, the operator disengages the interlock 544 from thelocking element 550 and then slides the housing 540 relative to thecontrol module 532 to remove the energetic module 526.

The control module 532 includes a housing 552 that includes a couplingelement 554 that cooperates with the coupling element 548. Disposed onthe end 556, adjacent to the locking element 550 is a visual indicator558. The visual indicator 558 is configured to display a different coloror symbol based on the operational setting (e.g. safe or armed).

Disposed within the housing 552 is an electronic safe and arm circuit560, a communications circuit 562, and a mechanical release assembly564. In an embodiment, the mechanical release assembly 564 includes asolenoid or servo 566 that engages a pin on the attachment plate 334(FIG. 4 ). When energy is applied to the solenoid 566, the solenoidretracts and releases its connection on the control module 532 andenergetic module 526.

It should be appreciated that since the payload module 530 includesenergetics 541, a safety architecture is incorporated into the assemblyto reduce the risk of inadvertent activation of the energetic 541. In anembodiment, the operation of the payload module 530 is guided by MilSpec MI-STD-1911, which provides for two independent inhibitingmechanisms to prevent unintentional arming of the energetic. As such thearming inhibits are removed by independent and sequential actions.

To accomplish this standard, two elements are used to interlock thearming of the energetic. First a feature on the attachment plate 334removes a pin 760 from the an energetic safety interlock 762 (FIG. 7 )when the payload module 530 is attached to the attachment plate. In anembodiment, the arrangement is configured such that a safety pin 760 canonly be removed and replaced when the payload module 530 is attached tothe attachment plate 334. Removal of the safety pin 760 closes switches764 to electrically couple the internal circuitry 700 to battery 766. Inother embodiments, the feature on the attachment plate 334 engages aswitch that disengages an interlock that holds/prevents-removal of thepin 760.

The payload module 530 is secured to the drone 20 by the solenoid 566.When energy is applied to the solenoid 566, a solenoid plunger movesfrom an extended position to a retracted position to release the controlmodule and payload assembly from the attachment plate. When the solenoidis not energized, the plunger retains the payload 526 to the drone 20.In an embodiment, the solenoid 566 is momentarily energized when theenergetic payload is attached. Power is removed when the safety pin 760is removed or disengaged. When an operator sends the command to releasethe energetic, such as via communications circuit 562 for example, thesolenoid 566 is once again temporarily energized causing the solenoid566 to retract and allow the control module and payload 526 to decouplefrom the attachment plate and move away from the drone 20 under theinfluence of gravity. In an embodiment, once the payload module 530separates from the attachment plate, the solenoid 566 is deenergized toavoid draining the energy-source/conserve-energy.

In an embodiment, the arming circuitry 700 includes a first portion thatprovides safety logic 768 and a second portion 770 that generates andtransfers a high-voltage fire pulse to initiate a low energy explodingfoil initiator (LEEFI) 774 to activate the energetic 741. It should beappreciated that while embodiments herein may refer to the use of aLEEFI to activate the energetic, this is for example purposes and theclaims should not be so limited. In other embodiments, other componentsmay be used, such as but not limited to an exploding bridge wire (EBW)detonator or a hot bridge wire (HBW) detonator for example. Two-wayradio frequency circuits 772 are provided to allow the operator toinitiate operation. In an embodiment, the power is provided by areplaceable and rechargeable battery 766.

The circuit 700 is energized when the pin 760 is removed andcommunication is established when the key FOB 777 is inserted into anoperator controller 800 (FIG. 8 ). In an embodiment, the key FOB 777includes a connector, such as a USB connector that couples with theoperator controller 800. The key FOB 777 when coupled with the operatorcontroller 800 allows the operator controller 800 to transmit codedsignals to the control module which the key FOB 777 is associated. In anembodiment, when communications are established, the circuit 700performs a power-on test to verify system readiness to perform amission.

It should be appreciated that in the embodiment of FIG. 8 , thecontroller 800 includes two sets of controls that allow the controllerto remove inhibits (e.g. arm), release the system 330, and fire/activatethe payload 326. Two sets of controls are provided to allow the controlof the two systems 330 to be operated independently.

In an embodiment, two signals from the operator are used to control andarm the energetic module 526. A first coded (e.g. encrypted) signal issent by the operator when the drone 20 has reached a safe separationdistance. This action closes one of the static arming inhibit switches778A. The second coded signal is the command to release the payloadmodule 530 and closes the other static arming inhibit switch 778B. Atimer within control logic gives the drone 20 the opportunity to movefrom the area before automatically closing the dynamic arming inhibit780 (in response to the expiration of the timer), which then charges thehigh voltage firing capacitor 782 which receives electrical power from ahigh voltage converter 784. At this time the energetic 741 is fullyarmed. In an embodiment, once the second coded signal is received, thesolenoid is deenergized to conserve energy. A third (final) signal fromthe operator is used to operate the firing switch 786, which leads todetonation of the energetic 741 by the LEEFI 774. The circuit 700 willsterilize the payload 526 if the energetic 741 is not commanded todetonate within a predetermined amount of time, or when power level inthe battery 766 drops below a predetermined level.

In an embodiment, until the point where the second signal is transmittedand received, the energetic may be returned to a safe condition and thedrone 20 moved back to the operator. In an embodiment, the operatorreturns the energetic to a safe condition by cancelling the first signal(safe separation distance), which opens one of the static arming inhibitswitches 778. When the drone 20 lands adjacent the operator, theoperator removes the key FOB 777 from the controller and replaces thesafety pin 760 to disconnect the battery 766 from the circuit 700.

It should be appreciated that material used in the energetic 741 mayinclude fragmentary rounds, high explosives, thermite, shaped charges,or non-lethal effects such as sound, pyrotechnics, smoke, or otherdisorientation or distraction effects.

In an embodiment, the operation of the payload 526 is controlled by ahandheld remote device. The handheld device is configured to encode thepayload 526 over an encrypted channel. In an embodiment, the handhelddevice is separate from the drone 20 controller. It should beappreciated that this provides advantages in allowing the operator theflexibility to move the system 30 between drones 20.

Referring now to FIGS. 9A-9C, another embodiment of the system 930. Thesystem 930 includes a control module 932, a payload 926, and a mountingplate 934. The control module 932 includes a pad 933 that is disposed ona top surface 935. The pad 933 may be made from an open or closed cellfoam material for example. The pad 933 is disposed between the topsurface 935 and the bottom surface of the plate 934 to reduce thetransfer of vibrations from the drone and the control module 932. Thepad 933 includes an opening 935 that is sized to receive the pin 928 onplate 934.

In this embodiment, the control module 932 includes an antenna 970. Inan embodiment, the antenna 970 is rotationally coupled to the side 953of the housing 952. Being able to rotate the antenna 970 providesadvantages in allowing the antenna to be repositioned depending on thefuselage geometry of the drone and the payload. On a first end 955, akey FOB 977 is coupled via a universal serial bus (USB) port. Similar tothe FOB 377, the FOB 977 allows the control module 932 to pair forcommunications with a handheld controller used by the operator.

On an opposite end 956, a separate mechanical interlock pin 960 extendsoutward from the housing 952. In an embodiment, the interlock pin 960 isretained to the housing 952 by a detent mechanism 961. As discussed inmore detail herein, in an embodiment the removal of the interlock pinactivates a timer the initiates selected operating components of thecontrol circuitry (e.g. internal circuitry 700). Also disposed on theend 956 is an actuator 963. The actuator 963 is electrically coupled tooperate an internal servo or solenoid (e.g. servo 566). In anembodiment, the activation of the actuator 963 causes a movement of acam that allows the pin 928 to be received by the control module 932.When the pin 928 is inserted, and the actuator 963 is released, the camengages the pin 928 to mechanically couple the control module 932 to theplate 934. Arranged adjacent the actuator 963 and the interlock pin 960is a visual indicator 958, such as an light emitting diode (LED) forexample. In an embodiment, the indicator 958 will emit light of apredetermined color to indicate to the operator the state of the controlmodule 932. For example, the emitting of a green light may indicate thatthe pin 960 is removed and the operator should move to a predetermineddistance away before a timer expires. The emitting of a yellow light mayindicate that the mechanical interlock has been removed and portions ofthe control circuit are active.

In an embodiment, the end 956 further includes a feature that cooperateswith a latch member 944 of the payload 926. When the latch 944 engagesthe feature, the payload 926 is mechanically coupled to the controlmodule 932 (e.g. the payload will not slide relative to the controlmodule).

In this embodiment, the plate 934 includes a planar portion 935 having aplurality of holes 937 that are arranged and sized to allow the plate934 to mount to a variety of different drone/vehicles. Extending fromthe planar portion 934 are a pair of ribs 939. The ribs 939 are arrangedon either side of the pin 928. The ribs 939 prevent side to sidemovement of the control module 932.

Referring now to FIG. 10 , an embodiment is shown of a system 1030having a mounting plate 1034 that is coupled to a vehicle, such as adrone 120. The system 1030 further includes a control module 1032 and aplurality of payloads 1026A, 1026B, 1026C. In an embodiment, the controlmodule 1032 is the same as that described herein with respect to controlmodules 332, 532, 932. It should be appreciated that in some situations,more than one type of payload may be desired to accomplish the desiredgoal. For example, where an energetic payload is being delivered, morethan one type of energetic may be used to neutralize a target. Where thepayload is delivering an article such as medicine or medical supplies,more than one type of medical supply may be desired. In this embodiment,the top most payload 1026A is removably coupled to the control module1032 in a similar manner as described herein and is fixed in place by aclip or fastener 1044. The subsequent payloads 1026B, 1026C are thencoupled in series to the first payload 1026A in a similar manner (e.g.slidably engages the previous payload and is secured with a clip).

In another embodiment, the control module 1032 may be configured toselectively uncouple the payloads 1026A, 1026B, 1026C to place thepayloads at multiple target locations. In this embodiment, each of thepayloads 1026A, 1026B, 1026C may include control passthrough that allowssignals from the control module 1032 to be transmitted to the desiredpayload.

Referring now to FIG. 11A, 11B, another operator controller 1100 isshown for use with any of the systems 830, 530, 930, 1030 describedherein. In this embodiment, the controller 1100. The controller 1100includes a housing 1102 that includes a port (not shown) configured toreceive a FOB, such as FOB 777, 977 for example, that allows one or moreprocessors or circuits within the controller 1100 to communicate withthe system 830, 530, 930, 1030. The controller 1100 further includes anantenna 1104 that is configured transmit signals to, and receive signalsfrom the system 830, 530, 930, 1030. The controller 1100 includes anactuator 1106, such as a slide switch for example, that turns-on oractivates the controller 1100. In an embodiment, an indicator, such asLED 1108, emits light when the controller 1100 is activated.

Typically the first step in setting up the controller 1100 is to pairthe controller with the system 830, 530, 930, 1030. This is done byinstalling the USB FOB 777, 977 in the port and then depressing anactuator, such as button 1110 for example, for a predetermined amount oftime (e.g. 5 seconds) until an indicator, such as LED 1112 startsflashing. In an embodiment, the operator then releases and immediatelydepresses the button 1110 again. At this point, if successful, thecontroller 1100 is paired with the USB. In an embodiment, the power LED1108 emits green light when the pairing is completed. In an embodiment,any other LED's on the controller 1100 will flash until the controlleris paired with the control module 332, 532, 932, 1032.

In an embodiment, the FOB 777, 977 is removed from the controller 1100and then installed on the control module 332, 532, 932, 1032. It shouldbe appreciated that at the point when the FOB 777, 977 is installed,there is only power to the servo motor or solenoid (e.g. no electricalpower to the firing circuit). The servo motor or solenoid only drawspower when the actuator on the control module, such as actuator 963 forexample, is actuated. The actuating of the actuator 963 allows thecontrol module 332, 532, 932, 1032 to be installed-on/coupled-to thevehicle/drone. In an embodiment, the FOB 777, 977 remains coupled to thecontrol module 332, 532, 932, 1032 for the duration of the mission.Where the payload includes an energetic, the FOB 777, 977 is eitherdestroyed or damaged to render it inoperable upon activation of theenergetic.

With the system 830, 530, 930, 1030 installed on the drone, the operatorremoves the pin 760, 960. In an embodiment, this activates a firstpredetermined timer (e.g. 30 seconds), that allows the operator to moveaway from the drone by a predetermined distance. When the time expires,the indicator 958 emits light, such as yellow light for example, toprovide a visual indication that power is available to the next level ofsafety inhibit (e.g. static arming inhibit 778A, 778B). In anembodiment, the removal of the pin 760, 960 further initiates a secondpredetermined timer (e.g. 60 minutes). If the second timer expires, allvoltage to the high voltage converter 784 is removed/turned-off. In anembodiment, when the second timer expired, power to the servo motor orsolenoid remains so that the system 830, 530, 930, 1030 may be removedfrom the drone.

In an embodiment, if the pin 760, 960 is reinserted into the controlmodule 332, 532, 932, 1032, electrical power is removed from the staticarming inhibit. 778A, 778B and the first and second timers are reset.

With the pin 760, 960 removed, the control module 332, 532, 932, 1032established communication with the controller 1100 based at least inpart on data stored on the FOB key 777, 977. In an embodiment, whencommunication is established between the controller 1100 and the controlmodule 332, 532, 932, 1032, the indicators/LED's on the controller willstop blinking/flashing.

During operation, the operator will typically move the drone apredetermined distance away and then move the arming actuator 1114 froma first or “safe” position to a second or “armed” position. In anembodiment, the indicator/LED 1116 emits a light, such as a red lightfor example. In an embodiment, this closes the static arming inhibit778A, 778B.

The drone is then moved to the desired location (e.g. the targetlocation). At the desired time, the operator opens the drop cover 1118to expose an actuator, such as a first toggle switch for example. Uponactuation of the first toggle switch, a first signal is transmitted fromthe controller 1110 to the control module 332, 532, 932, 1032. When thefirst signal is received. the servo motor or solenoid is activatedallowing the control module 332, 532, 932, 1032 and any payloads 326,526, 926, 1026A to move away from the plate 334, 534, 934, 1034 underthe influence of gravity. In an embodiment, the receiving of the firstsignal initiates a third predetermined timer (e.g. 5 second timer),which prevents the arming of the high voltage converter 784 to providesufficient time for the system to fall out of the way and for the droneto move away from the payloads.

Finally, the operator lifts a fire cover 1120 to expose an actuator,such as a second toggle switch for example. Upon actuation of the secondtoggle switch, a second signal is transmitted from the controller 1110to the control module 332, 532, 932, 1032. The receiving of the secondsignal causes the control module 332, 532, 932, 1032 to close thedynamic arming inhibit 780 causing electrical power to flow from thesystem battery 766 to the high voltage converter 784 and charge thefiring energy storage 782. The energy from storage 782 is rapidly flowedto the detonator 774.

It should be appreciated that in an embodiment where the payload is anarticle, such as medical supplies for example, the operator will notneed to activate the second toggle switch.

In the event that there is a mis-fire, or if the mission of the drone isabandoned, the drone can be moved to a desired location, such as awayfrom personnel and allowed to rest for a minimum of the length of timeof the second timer (e.g. 60 minutes) so that energy is removed from thecontrol module 332, 532, 932, 1032 except for the power to the servomotor or solenoid. The operator may turn of power to the controller 1100(e.g. actuator 1106) and optionally remove the battery from thecontroller 1100. The operator then approaches the drone and reinsertsthe pin 760, 960 and removes the FOB 777, 977. By pressing the actuator963, the system 330, 530, 930, 1030 may be removed from the drone andthe payload 326, 526, 926, 1026A separated from the control module 332,532, 932, 1032. In an embodiment, the energy source (e.g. battery) isremoved from the control module 332, 532, 932, 1032.

It should be appreciated that while embodiments herein describe thesystem 20 as having a pair of energetic payloads arranged in parallel,this is for example purposes and the claims should not be so limited. Inother embodiments, the system 30 may have a single energetic payload, ora plurality of energetic payloads to meet the goal of the mission thedrone is undertaking.

Technical effects and benefits of some embodiments include the abilityto allow a drone to deliver a payload where the payload is independentlyoperable from the drone. Still further embodiments provide technicaleffects and benefits of allowing a single payload system to beinteroperable with a variety of drone manufacturers without changing theoperation of the payload system. Still further embodiments providetechnical effects and benefits of providing a flexible payload systemthat can carry one or multiple energetics depending on the goal of themission. Still further embodiments provide technical effects andbenefits of allowing a drone to be used on a mission and returned forreuse or redeployment.
